APPARATUS FOR INHALING'IVIEDICINAL VAPORS, 86C.

SPECIFICATION forming part of Letters Patent No. 376,819, dated January24, 1888. Application filed Septembzr 27, 1887. Serial'No. 250.845. (Nomodel.) I

To all whom it mayv concern:

- Be it known that I, FREDERICK HARRISON GLEW, of 30 Conduit Street,Bond Street, in

the county of Middlesex, England, have invented certain new andusefulImprovements in Apparatus for Inhaling or Injecting Medicinal Vapors,Gases, or Powders, of which the following is a specification.

In the construction of an apparatusaccord IQ ing to my invention Iemploy a large-mouthed bottle or vessel of glass or other suitablematerial, the mouth of which I close with a suitable stopper or plug. Inthis stopper or plug I secure in any convenient manner three or moretubes, in two or more of which I place any suitable porous material,such ascylinders of pumice or Woven cords of asbestus saturated with thechemicals to be used in the formation of the remedial agent -say, forex-. ample, chloride of'ammonium or the remedial agents themselvestobeinhaled. Theremaining tube, which is to be used as a suction tube, Iconstruct with its inner end enlarged to form a receptacle for a spongewithin the I bottle or vessel.

The porous cylinders or cords, the Sizes and lengths of which. areadjusted so as to take up the requisite proportions of the chemicalsnecessary to formthe proper combination for 0 inhalation, are,whencharged, placed in their The sponge placed in the.

material, C, which carries the chemical substances for forming thecompound remedial agent, and D is the suction-tube, thelower end ofwhich is enlarged to receive a piece of 5 sponge, D. I To the other endof this tube D is secured a flexible tube, D, provided with a suitablemouth-piece, D or instead of this flexible suction-tube an enema or apump may their respective tubes for the purpose of being contact witheach other. Consequently the be attached for the purpose of injectingin' place of inhaling the remedial agent. In order to prevent mistakesin charging the porous materials,I make the tubes 0 of colored glass,and the tube 0 ofwhite'glass, and in sending out theapparatus I placethe chemi' cal substances in similarly-colored bottles. f

The pieces of porous materiahG are each provided with a small piece ofsuitable 'wire, by means, of which they may be withdrawn from rechargedI I An inhaler constructed as above described embodies all the goodqualities of other inhalers, and as all the working parts are containedwithin the inhaler itself they are protected from breakageand theinhaler is sim- 165 plified in construction.

One importantadvantagein this construction is that bodies of liquids aredispensed with, a damp sponge being used in the Suctio'n-tube instead ofa body of water, in the-7o vessel A to absorb any excess of vapor,whether of ammonia or acid. Atthe same time the gurgling noise whichensues whenairis drawn through a liquid is'avoided. The

effortof suction is also reduced to a mini- 7 5 i mum, as the bottle Acontains no body of water. There is also no loss of vapor of chloride ofammonium through absorption in that liqu'idand no deterioration of theagents from product is uniformly as neutral as it can be practicallyobtained for inhalation. 1

Another advantage that this form 0t: in-

haler possesses is, that if inadvertently the patient should, instead ofsucking, blow into the .8 5

apparatus (a very common mistake) no inconvenience can result; "neithercan the acid or ammoniabe damaged. 7 A further advantage is that theapparatus affords facility 'for the use of remedial agents in the formofpowder. o When'em'ploying such agents,a piece of dry sponge is placedin the enlarged receptacle provided at the lower end 01 thesuction-tube, and powdered remedial agents may beplaced at the bottom ofthe vessel A, the draft of, air 5 caused by suction being in such casesufficient to stir up and suspend them in the body also fitted to saidstopper, and having its in of theinhaleigand their filtration beingeffected ner end enlarged to form a receptacle for a by their passagethrough the dry sponge into sponge, substantially as herein described.the suction-tube.
